Ewon Security Enhancement (FW 11.2s2)

eWON reference: Webserver - eWON authentication mechanism improvement

Affected devices: All
Affected firmware versions: All

A non-authenticated user could get access in read only to some eWON device information.

Mitigation Factors:
As a rule, we recommend:

  • to avoid making eWONs devices being directly reachable from non-trusted user by using a firewall and an access control policy.
  • for remote access, use a secure remote access solution like Talk2M.

Install the last firmware version. This has been fixed as from version 11.2s2.
